This billboard with a picture of the President handing over a tree to the Mayor can be seen in several places in the city. The writing on it says "No Day Without Tree Planting".
The billboard is part of the nation's wider campaign for Planting 1 Billion Trees Movement (called OBIT -- One Billion Indonesian Trees) which began in 2006.
The movement, which becomes part of Indonesia's commitment to curbing global warming, is commemorated every year on November 28. This year, the President launched the tree-planting-month-of-December campaign to speed up the achievement of 1 billion tree target and to encourage every citizen to take part in the movement.
This year's commemoration theme is "Hutan Kota Mendorong Terwujudnya Indonesia Hijau" or Urban Forest for Green Indonesia.
